HTPC chassis sanded or sand blasted?

Wesena makes e series chassis with flat surfaces sanded, and corners sandblasted. (Attached picture)
They consider chassis with flat surfaces sandblasted like corners. I think that their models are unique because of this combination, but this is my opinion.
What do you think, guys? Sandblasted corners only or sandblasted all surfaces, top included of course.

I added picture of e7 sandblasted.

Only five people have opinion? Not to many.
